SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 360,064, dated March 29, 1887.

A pplicaiion filed July 30, 1850. Serial No. 209,517. (ModeL) To all whom it may concern.-

Be it known that I, THEODORE F. TIMBY, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Sash-Fastenings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The present invention relates to that class of sash-fasteners that are designed to be placed in the sash-frame of a window and that are provided with two independent belts or dogs arranged to respectively engage the upper and lower sashes for the purpose of holding them locked in a closed or other position.

Heretofore such sash-fasteners have usually been constructed in so many parts as to render them complex and unwieldy in their action as well as costly to produce. Such fasteners have further and particular objections in that they have not been properly constructed with reference to being readily adjusted upon windowframes having sashes of varying thicknesses; and, furthermore, in that their external thumb piece or other operating device has generally been arranged so that it became an obstruction to inside blinds and to screens.

It is the object, therefore, of my invention to provide a sash-lock that, by the simplicity of its parts and construction and by the arrangement of such parts, shall obviate the objections referred to as existing in the sashfasteners now in use, and being separate from the parts carrying the bolts, so that it can be adjusted relatively to the bolts.

The invention consists of two rocking and spring-actuated sash-bolts, which are shaped at one end into the form ofdogs that areadapted to engage the sashes, such bolts being arranged side by side and extending transversely of the sash-frame to the front or inner side thereof, where they terminate each in a crank or lever arm, which respectively bear upon the opposite sides of a sliding lug, this lug being provided with a thumbpiece, by which it may be operated to rock either of the bolts, and thereby withdraw the engaging-dog of such bolt from the sash that it holds.

In the drawings, Figure 1 is a face view of a sash-frame, showingasash-fastener embodying the invention attached thereto. Fig. 2 is a cross-section of the same parts on the line as .r. Fig. 3 is an edge view of the plate carrying the slide for operating the bolts, and Fig. 4 is a rear view of the same.

Referring to these views in detail, A represents the sash-frame, and B, Fig. 2, parts of the sashes in place in the ways 0 of the frame, D being the inside saslrstop.

E is a metallic case of the form shown, and secured to the sash-frame in a suitable mortise. This case supports in suitable bearings the bolts F F, which may be of common wire of large size bent into shape, and they lie side by side in such case.

G G are the dogs on these bolts, these dogs being attached to the bolts at right angles thereto, and their dogging ends project through the'case so as to enter holes or mortises in the edges of the sashes, and thereby hold the sashes. The other ends of these bolts are bent outward at right angles to their body part, so as to form the lever or crank arms H H, which arms also curve upward from and then downward toward each other, as shown.

I is a bevel-shaped lug arranged between the arms H H, and is carried on the slide J, which is secured to the under side of the plate K by ways L and pins M. The slide-plate is provided with a thumb-piece, N, which projects through a side recess in the plate K, secured to the face of the inside sash-stop, C, and serves to operate the sash-dogs.

O is a spring surrounding one of the bolts F, and engaging the other bolt in such manner that its tension constantly acts to hold the dogs against the sashes.

The operation will now be plain. Simply pushing the thumb-piece up or down causes the bolt thereby operated to rock, and thus withdraw its dog from the sash that it holds, while the spring on the bolts will act upon releasing the thumb piece to return the bolt to its normal position of bearing upon the sash.

It should be particularly noted that the lug I is carried on supports separate from the sup ports of the bolts, and has extending bearingsurfaces for the arms H H, both in the direction of said arms and laterally to them. This permits of the slide-plate being arranged in various different positions relatively to such arms without affecting their operative relation. By this means the fastener may be readily attached to sash-frames having different widths of inside side stops or sashes of different thicknesses and without any special fitting of the parts. This same feature of adjustability permits of the plate K being placed so that the thumb-piece N will in no way interfere with the operation of an inside blind or screen, the thumb-piece being located thereon in such a position that for such applications of the fastener it is where it will not act as an obstruction.

The parts composing this fastener are manifestly capable of various modifications, and hence I do not confine myself to their exact form onconstruction.

I am aware that sliding bolts having sashengaging stops and operated by a rocking thumb-piece attached to the same carryingplate as the bolts are old; also, that rocking dogs arranged upon a single shaft, or upon sep arate but interlocking shaft-like supports, and

operated by swinging thumb-pieces, are not new, and I do not claim these as my invention.

What is claimed as new is 1. The combination, in a sash-fastener, of two independent rocking sash-bolts arranged in suitable supports and provided at their outer ends each with a dog adapted to respectively engage the upper and lower sashes, and at their inner ends with a crank-arm, a spring for normally holding said dogs against the sashes, and a slide having a lug arranged in the path of said arm, substantially as described.

2. The combination, in a sash-fastener, of the bolts F F, independently arranged, as shown, and provided with the dogs G G and crank-arms H H, the spring 0, and the slide J, having the lug I and thumb-piece N, for use and operation substantially as described.
